Application filed October 26, 1910. Serial No. 589,237.

To all whom it may concern:

Be it known that I, HUGo CASSIRER, a citizen of the German Empire, residing at Charlottenburg, in the Kingdom of Prussia, German Empire, have invented new and useful Improvements in Machines for Making Dress-Shields of India-Rubber, of which the following is a specification.

The present invention relates to an arrangement for manufacturing dress shields of india-rubber. Such dress shields are limited by two curves transecting each other one concave and one convex curve. Each -shield 'consists of two such india-rubber exemplification leaves placed one on top of the other and secured to each' other along the concave curve (the arm hole curve). I For manufacturing such dress shields hitherto a large number of sheets of india-rubber were arranged in a pile and the singleleaves were then cut out with a knife passed along a templet or punched out by means of a suitably shaped die. The convex curve thereby received at once its proper shape, while on the concave talnpiece wider. In consequence of such cutting or stamping operation the single leaves would slightly stick to each other. The leaves had'therefore to be subsequently separated, always two at a time. Then these leaves, which still adhered to each other were parted at the convex curve. Then each pair of such leaves were cut by means of a heated handpress along the concave curve to the proper length and shape and thereby the two leaves were simultaneously pasted together at the concave curve fpr the armhole. This tedious procedure and such expensive ha nd-work is avoided by the present process, automatic mechanical operations being substituted therefor.

In the drawing a machine is shown as an by which the dress shields can be manufactured according to the new method.

Figure 1 is a side elevation of the machine shown partly in section; Fig. 2 is a plan; Fig. 3 is a cross section along AB in Fig. l (seen from the right); Fig. 4 is a cross section along CD in Fig. 1 (seen from the right).

e machine operates in the following manner: Two lengths of india-rubber cut 0 the necessary width and woumd up in rolls are placed on two spindleso, a which side the leaves thus cut out were left a cerare supported in such a manner on swinging holders 6, b fitted to the machine frame 4), that they may be either rested against or raised from an endless belt conveyer c traveling over guide drums c 0 arranged at the ends of the frame 1:. The lengths of india-rubber are now intermittently advanced by means of the belt conveyer 0. Between each two successive advances there is a stoppage of some length, during which at one point of the machine the arm hole curve f is punched out and at the same time the two pieces of india-rubber are pasted together along this curve, and at another point of the machine (following inthe direction of travel of the material) the convex curve 9 is cut out. All movements are produced by a shaft 72., which is arranged on the one side of the machine and which is driven by means of a chain wheel k or in any other suitable manner. The intermittent motion of the conveyer belt 0 togetherwith the india-rubber material on it is produced by the intermittent rotation of drum 0. Shaft it drives by means of bevel gears b 7& of equal size'a' shaft 2' at the same speed. At each revolution of shaft 1' a pin 2' turns, in known manner during part of such revolution, a lHaltese cross 1: by one division. During the remainder of each revolution of shaft 2', the Maltese cross 1: is prevented by disk 27 from turning any farther. The spindle 10 of the Maltese cross drives by means of change wheels k is", k, k the drum 0*. The change wheels are so adjusted with relation to each other, that the length of the arc through which the drum 0 is rotated and thus also the distance the belt a and the india-rubber material on it are advanced, are regulated as may be desired. fore advanced at each revolution of the shaft 72 a certain distance and then remain stationary for a certainlength of time. The conveyer belt 0 and the india-rubber on the same are heated during part of t'eir travel by means of plate a heated by Bunsen burners.

The punch e for cutting out the arm hole curve is arranged vertically adjustable in an upright frame d; said punch consisting of a steel blade ground at its lower edge to a cutting edge, and is adjusted before starting of the machine by suitably provided means to the armhole curve required. The spindle e at each of these travels the indie-rubber along the convex curve 9 it is automatically raised and remains in such raised position until the belt conveyer c and with the latter carrying the cutter e is vertically moved by means of double armed levers 1 (Fig. 4) which are arranged to swivel at l on frame (I.

These dress shields may then be immediately vulcanized, separating the two leaves at the convex curve being dispensed with.

By means of the hereinbefore described machine one attendant will be able to turn out within the same time about four times as many dress shields as was hitherto possible by handwork.

I claim:

The upper end 0 rod m projecting beyond the cutter holder m carries an arm m. At the end of the oscillating motion, which the cutter 0 er receives (both in one and the other direction of oscillation) the arm m will roll upon a lug 9 one of which is provided at each end of the curve disk 9 Hereby arm m and rod m are raised contrary to the action of sprin m and the cutter m is thereby lifted rom the india-rubber material. At each revolution of the driving shaft It therefore the cutter (by the arm m rolling off from the lug 9 is pressed into the indiamubber strips. The cutter m is then swung along in the one direction and cuts the curve 9 and is again lifted at the far end of its travel. Now the india-rubber strips are advanced, the cutter m is again lowered and now cuts the following curve 9 traveling this time in the opposite direction. As the curve disk 1 is arranged in such a manner, that it can e easily exchanged, any desired curve 9 may be cut by employing a corresponding curve disk.
